Uniformly Most Powerful Test - Setting

Setting

Let denote a random vector (corresponding to the measurements), taken from a parametrized family of probability density functions or probability mass functions, which depends on the unknown deterministic parameter . The parameter space is partitioned into two disjoint sets and . Let denote the hypothesis that, and let denote the hypothesis that . The binary test of hypotheses is performed using a test function .

\phi(x) =
\begin{cases}
1 & \text{if } x \in R \\
0 & \text{if } x \in A
\end{cases}

meaning that is in force if the measurement and that is in force if the measurement . Note that is a disjoint covering of the measurement space.

Famous quotes containing the word setting:

    We don’t arrive at it by standing on one leg or on the first day of our setting out—but though we may jostle one another on the way that is no reason why we should strike or trample—elbowing’s enough.
    George Gordon Noel Byron (1788–1824)

    Teaching Black Studies, I find that students are quick to label a black person who has grown up in a predominantly white setting and attended similar schools as “not black enough.” ...Our concept of black experience has been too narrow and constricting.
    bell hooks (b. c. 1955)

    High from the summit of a craggy cliff,
    Hung o’er the deep, such as amazing frowns
    On utmost Kilda’s shore, whose lonely race
    Resign the setting sun to Indian worlds,
    The royal eagle draws his vigorous young
    James Thomson (1700–1748)
